Everyone knows that human excrement must be sanitarily and environmentally treated before discharge into our waterways or when taken from septic tanks. What most people don’t know is that millions of tons of farm animal excrement are put into the environment totally raw and untreated. Much of the polluting nutrients and bacteria wind up in the Chesapeake Bay’s creeks and streams or in groundwater destroying water quality.

When 13 million people in the Bay watershed flush their toilets, the wastewater flows through miles of pipes and many pumping stations to the nearest treatment plant. These plants must meet stringent federal and state standards for destroying disease-causing organisms and for removing environmentally harmful chemicals and nutrients. The plants must keep comprehensive records and are repeatedly inspected for Clean Water Act compliance. The public has full access to all such records and can even sue should any plant violate its strict permit limits.
